Hoerbiger-Origa launches heavy-duty OSP linear actuator

Hoerbiger-Origa is launching a heavy-duty version of its popular OSP linear actuator, based around a four-row recirculating ball bearing guide and a polished, hardened steel guide rail.

Manufactured in sizes 25 to 50, the OSP-HD unit can handle loads up to 18000N. As with the existing OSP models, the new versions are available with either an electric or rodless pneumatic drive.

Designed to carry heavy loads and high moments, the HD unit has a twin-guide rail construction to give a high level of load support and rigidity. The precision guide rails are mounted on single-piece aluminium profiles and coupled to the actuator via dovetail mounting grooves in such a way that maximum rigidity and loads can be borne in all directions.

The mounting profile includes T-slots for attaching sensors and they can also accommodate Hoerbiger-Origa's new SFI-PLUS incremental encoder for real-time position monitoring. A cover is provided for the slots, which can be positioned after the sensors are mounted to protect and contain their cables. For simple limited-stroke applications, the slots can be used to hold mechanical stops, for which a range of shock absorbers is available.

In multi-axis handling applications, the OSP-HD's high level of rigidity and load capacity are major advantages. When used in combination with other multi-axis modular components from Hoerbiger-Origa, automation of even complex handling tasks can readily be achieved.

Further application areas include assembly machines, vertical installations with high cantilever loadings, x-y tables, and applications demanding precise and repeatable movements (particularly when using the screw-driven versions).

The rigour of detail design that runs through the whole OSP actuator family reflects machine builders' increasing requirement for total rationality in the components and subsystems they incorporate into their designs. This reduces their design effort, rationalises their stock holding and simplifies procurement. Significantly, it also makes their machines more easily reconfigurable and adaptable for a long working life.
